reset key/name when TableValuedColumn is adapted
Fixed issue in new :meth:`_schema.Table.table_valued` method where the
resulting :class:`_sql.TableValuedColumn` construct would not respond
correctly to alias adaptation as is used throughout the ORM, such as for
eager loading, polymorphic loading, etc.
Fixes: #6775
